The company is considering shipping products based on customers’ previous orders and shopping habits, like searches, wish lists, and shopping cart contents.

Here’s how it would work: Amazon would box and ship products it expects customers to request, then the packages would wait at a shipping hub (or in a truck) until your actual order arrives. Amazon says it’s an attempt at cutting delivery time.

It’s not clear if Amazon has deployed or will deploy the technique. A spokeswoman declined to comment.
